A new Progressive Management Pathway for improving seaweed biosecurity. Nature C...

Gracilaria aquaculture is one of the fastest-growing sectors, contributing to 10.5% of the global seaweed feed-stock supply-chain in 2019. It predominantly caters to food-grade agar, animal feed, and non-food sector applications viz. biotechnology, biomedical, and pharmaceuticals. It has witnessed a rapid expansion triggered by increased demand due...

Seaweed aquaculture biosecurity measures were implemented at the farm level to assess their effectiveness on the occurrence of diseases and epiphytes, correlation of environmental parameters to disease occurrence, and effect on the growth rate and carrageenan properties on the commercially important red seaweeds Kappaphycus alvarezii and Eucheuma d...

Seaweeds form the second largest global aquaculture product in volume, and despite rapid growth of the sector over the last 25 years, production and quality in top producing regions is becoming increasingly limited due to disease and pest outbreaks, the spread of non-native cultivars and the degradation of genetic health due to inbreeding. Most not...

Sustaining economic interest in Malaysian seaweed cultivation and ensuring price stability will require coordination of downstream value chain activities including marketing and trading.-Incentives and financial support for Small Medium Enterprises (SMEs) and private sector investments could spearhead innovation in diversified seaweed-based value-a...

Highlights 1. This policy brief highlights key challenges that must be addressed for the long-term sustainability of the global seaweed industry, ensuring its role in providing nature-based solutions within the sustainable ocean economy agenda and in contributing to the UN Decade of Ocean Science for Sustainable Development (2021-2030). 2. Seaweed...

Embedding the biosecurity concept in the management of the eucheumatoid aquaculture industry, will support growth of the industry and protect it from loss caused by persistent diseases and pests. Achieving effective on-farm biosecurity measures is essential to securing sustainable production of the high-value seaweed crop. The GlobalSeaweedSTAR pro...

This Standard Operating Procedure (SOP), provides basic guidelines for farm practitioners to be used in the cultivation of eucheumatoid seaweed. These guidelines contribute to progress in understanding and managing the biosecurity risks inherent in the seaweed eucheumatoid farming system, and aim to provide clear instructions from preparation to po...

The application of biosecurity in seaweed aquaculture plays an important role in reducing the impact of disease and pest outbreaks. The continuous occurrence of seaweed pests including the macroalgal epiphytes, epi-endophytic filamentous algae and biofilms on Kappaphycus farms may also potentially induce further incidences of the ice-ice syndrome....

This study evaluated on-farm implementation and effectiveness of Malaysian seaweed aquaculture policies and regulations that applied the biosecurity concept. The knowledge-attitude-practice (KAP) survey tool was utilised to assess the effectiveness of the biosecurity measures adopted by seaweed stakeholders, including 67 seaweed farmers and ten gov...

Seaweeds account for nearly 30% of global aquaculture production by volume, and their cultivation provides important opportunities for employment and wealth generation, particularly in rural coastal communities. Eucheumatoids (Kappaphycus and Eucheuma spp.) are tropical red algae commercially cultivated as raw material for production of carrageenan...

Each year a significant proportion of global food production is lost to pests and diseases, with concerted efforts by government and industry focussed on application of effective biosecurity policies which attempt to minimise their emergence and spread. In aquaculture the volume of seaweeds produced is second only to farmed fish and red algal carra...

Indonesia is the world largest producer of the red seaweeds Kappaphycus and Eucheuma; however, this country is facing significant challenges such as disease outbreaks, epiphyte infestations and a loss in seedling quality. Biosecurity practices have been widely adopted in other aquaculture sectors and when enforced can help to limit the introduction...

Ulva are ubiquitous and opportunistic green algae species that easily adapt to various environmental conditions. These algae are responsible for the green tides that cause many environmental and ecological problems in coastal waters. We investigated the physiological responses of Ulva australis under warming, acidification, and eutrophication condi...

There has been increasing interest in promoting the seaweed Kappaphycus alvarezii as a co‐culture species in an integrated multitrophic aquaculture system. In recent work, we observed the capability of K. alvarezii to grow and remove carbon (C), nitrogen (N), and phosphorus (P) when planted in an intensive fish floating‐net cage system in Sekotong...

The anaerobic ammonium oxidation (anammox) process is well-known as a low-energy consuming and eco-friendly technology for treating nitrogen-rich wastewater. Although the anammox reaction was widely investigated in terms of its application in many wastewater treatment processes, practical anammox application at the pilot and industrial scales is li...

Ocean acidification (OA) and coastal eutrophication affect coastal marine organisms. We studied the physiological responses of Gracilariopsis lemaneiformis (Gracilariales, Rhodophyta) to increased concentrations of CO2 and NH4⁺. Incubation treatments were applied at two different pH units (low, 7.5; high (control), 7.9) and three different NH4⁺ con...

There has been ever increasing interest in Integrated Multi-Trophic Aquaculture System (IMTA) to encourage developing environmentally friendly aquaculture, which combines fed aquaculture with extractive aquaculture in proximity. IMTA can minimize the environmental impacts of conventional monoculture aquaculture farms while expanding their economic...
